[R] Filter operations not shown when called before summarise

### Describe the bug, including details regarding any error messages, version, and platform.

When I print an arrow dataset-query that involves filtering then summarising, the filtering operation is not shown.

For example:
``` r
library(arrow)
library(dplyr)
ds_file <- file.path(tempdir(), "mtcars")

write_dataset(mtcars |> select(mpg, cyl), ds_file)
ds <- open_dataset(ds_file)

# filter is printed | EXPECTED
ds |> filter(mpg > 25)
#> FileSystemDataset (query)
#> mpg: double
#> cyl: double
#>
#> * Filter: (mpg > 25) #<======
#> See $.data for the source Arrow object

# filter is NOT printed | EXPECTED
ds |>
filter(mpg > 25) |>
summarise(mpg = mean(mpg))
#> FileSystemDataset (query)
#> mpg: double
#> #<==== Missing?!
#> See $.data for the source Arrow object

# first is NOT printed | NOT EXPECTED!
# second filter is printed | EXPECTED
ds |>
filter(mpg > 25) |>
summarise(mpg = mean(mpg)) |>
filter(mpg > 0)
#> FileSystemDataset (query)
#> mpg: double
#>
#> * Filter: (mpg > 0) #<==== Missing mpg > 25 ?!
#> See $.data for the source Arrow object
```

I would expect to see the filtering as well as the summarise command of the query as well.

I use R 4.1.1 with arrow version 10.0.0

### Component(s)

R

Run the supplied R reproducer with Arrow 10.0.0, focusing on the printed output for chained filter() and summarise() operations. Trace the dataset-query print path from this example and verify that the initial filter and summarise operation remain visible alongside a later filter.
